In 1872, george Huntington presented his essay “On Chorea” to the Meigs and Mason Academy of Medicine and, in doing so, detailed a disease that would later bear his name. Huntington's disease(HD) is a genetic, neurodegenerative disease that manifests as the loss of motor control,cognitive impairment,and mood and psychiatric changes in paents.

Efforts on chemoprevention have been an attractive target of investigation for prostate cancer. Since prostate cancer is the most common non-cutaneous malignancy among American men, efforts for chemopreventative strategies make sense. However, such undertaking has been wrought with problems and wide-scale efforts to launch drug chemoprevent/on have been dampened by mixed results.

Inflammatory bowel disease patients are prone to immunosuppression due to effects of their medications. Physicians are recommended to assess vaccination status and overall health in all patients, prior to initiation of immunosuppressive therapy. Immunosuppressant medications in women with inflammatory bowel disease are often continued during pregnancy, which can result in newborns having an increased risk of immunosuppression at birth. While medication-induced immunosuppression in infants is transient, parents should be counselled about delaying live vaccine administration in newborns until they are immune competent. A retrospective study was done over six months at an urban multispecialty medical center to assess whether physicians are counselling pregnant immunosuppressed inflammatory bowel disease patients regarding live vaccinations in their newborns. The study revealed that only 57% of patients had documented counselling in their charts. Further studies are necessary to determine physician counselling practices of pregnant women about live vaccines. It is critical that physicians and patients are aware of the risks of immunosuppression in pregnancy and the potential impact of live vaccinesupon the newborn.

Total proctocolectomy with ileal pouch-anal anastomosis(IPAA) is the current gold standard in the surgical treatment of ulcerative colitis(UC) refractory to medical management. A procedure of significant magnitude carries its own risks including anastomotic failure, pelvic sepsis and a low rate of neoplastic degeneration overtime. Recent studies have shown that total colectomy with ileorectal anastomosis(IRA) has been associated with good long-term functional results in a selected group of UC patients amenable to undergo a strict surveillance for the relatively high risk of cancer in the rectum. This manuscript will review and compare the most recent literature on IRA and IPAA as it pertains to postoperative morbidity and mortality, failure rates, functional outcomes and cancer risk.
